SHEET COLLECTING AND ASSOCIATING MECHANISM.

Application filed May 21, 1918.

T0 all'wiwm it may concern:

Be it known that I, HOWARD M. BARBER, a citizen of the United States, and resident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Sheet Collecting and Associating Mechanism, of which the following is a specification.

In sheet collecting and associating mechanism it is very difficult to hold the sheets in register on the collecting cylinder as the grippers open to collect the sheets and open to transfer the sheets. This is especially true where a number of sheets are to be collected and associated and transferred and as cover sheets, fed from one source and insert sheets fed from another source; the side grippers serving to hold the sheets which are on the cylinder in register when the end grippers are opened to collect the main web sheets and to associate therewith the insert sheets and to transfer the associated and collected cover, main web and insert sheets to a transfer cylinder. The side grippers open beyond the sides of the sheets as the grippers pass the collection, insert association and transfer points so as not to interfere with the passage of the sheets.

A practical embodiment of my lnvention is represented in the accompanying drawings in which,

Figur 1 is a view in front elevation of so much of a sheet handling machine as includes my invention.

Fig. 2 is a section taken in the plane of the line n n of Fig. 1.

Fig. 3 is a section taken in the plane of the line IIIIII of Fig. 1.

Fig. at is a section taken in the plane of the line IVIV of Fig. 1, and

Fi 5 is a detail section showing one of the side grippers and one of its operating Specification of Letters Patent.

One or more webs pass over the web feed roll 1 and downwardly through the pair. of coacting cutters 2, 3, and guides 4, 5, to one of the two sets of grippers 6 of the main web sheet feeding cylinder 7. The combined collecting and associating cylinder 8 may have one or more sets of end grippers 9 and one or more correspondin sets of side grippers 10. In the present instance, I have shown the cylinder 8 as having five sets of end grippers and five sets of side grippers, the side grippers being located a considerable distance back of their end grippers so as to engage the sheets at about midway their length.

The cylinder 11 is an extra sheet feeding cylinder arranged to feed one or more extra sheets to each of the collecting and associating surfaces of the cylinder 8. In the present instance, this cylinder 11 is arranged to feed QOVBI sheets to the cylinder 8 at the proper intervals to be associated thereon with the collected main web sheets as will hereinafter appear.

The cylinder 11 is provided with a set of end grippers 12 arranged to take the covers from a suitable feed table 13 and transfer them to the end grippers 9 of the combined sheet collecting and associating cylinder 8. The cylinder 1% is another extra sheet feeding cylinder arranged to feed one or more extra sheets to each of the collecting and associating surfaces of the cylinder 8. In the present instance this cylinder 14 is arranged to feed insert sheets to the cylinder 8 at the proper intervals to be associated with the associated cover sheet and collected group of main web sheets thereon as will hereinafter appear. The cylinder 1a is provided witha set of end grippers 15 arranged to take the inserts from a suitable feed table 1 6 and transfer them to the end grippers 9 of the combined collecting and associating cylinder 8.

The cylinder 17 has a set of end grippers 18 arranged to take each group of collected and associated main web, cover and insert sheets from the end grippers 9 of the combined collecting and associating cylinder 8, at the proper times and transfer the so collected and associated sheets to a suitable folding mechanism, 37, 88.

With the arrangement of the parts as herein illustrated, the combined collecting of a revolution for each revolution of the cover feeding cylinder 11, the insert feeding cylinder 14 and the transfer cylinder 17. The main web sheet feeding cylinder 7 makes two revolutions for each revolution of the cylinders 11, 1a and 17 and two and onehalf revolutions for each revolution of the cylinder 8. The grippers 12 of the cover feeding cylinder 11 are tumbler operated and are closed to take the cover sheetsfrom the table 13 every revolution of the cylinder 11, by the coaction of the tumbler cam 19 with the tumbler pin 20. The grippers 12 are opci'zed to transfer their cover sheet to ,coaction of the tumbler cam 22 with the tumbler pin 23. The grippers 15 are opened to transfer their insert sheet to the end, grippers 9 of the cylinder 8, every revolution of the cylinder 14, by the coaction of the tunr bler cam 22, with the tumbler pin 2-1.

The grippers 18 of the transfer cylinder 17 are operated every revolution of the cylinder 17, by the fixed cam 25, to engage and grip the collected and associated main web, cover and insert sheets every one and onefifth revolutions of the combined collecting and associating cylinder 8.

A fixed cam 26 controls the operation of the grippers 6 on the main web sheet feeding cylinder 7, to take the sheets from the guides 5, 1, and transfer them to their respective end grippers 9 on the cylinder 8. A fixed cam 27 is arranged in position to successively control the operation of the end grippers 9 to take the main web sheets from the feeding cylinder 7. A movable cam 28 is moved in position every revolution of the cover feeding cylinder 11, by a rotary cam 29 to open a set of end grippers 9 to receive the cover sheet. A movable cam 30 is moved into position every revolution ofthe insert feeding cylinder 14, by a rotary cam 31 to open a set of end grippers 9 to receive an insert sheet on top of a collected and associated group of main web and cover sheets. A movablecam 32 ismoved into position every revolution of the transfer cylinder 17,

by a-rotary cam 33, to permit the transfer of the collected and associated group of main web, cover and insert sheets to the said transfer cylinder. The side grippers 10 are opened by the cams 34 as they pass the transfer point between the cylinders 7 and 8. They are again opened 'bythe cams 35 as they pass the transfer point between the cylinders 14 and 8, and they are again opened by the cams 36 asthey pass the transfer point between the cylinders 8 and 17. These last named cams 36 are sufliciently long to keep the side grippers open as they pass the transfer point between the cylinders 11 and 8. Itis to be understood that these side grippers are yieldingly held closed except when opened by the said sets of cams 34:, 35,

In the cycle of operations, a set of end grippers 9 on the cylinder which has just transferred a collected and associated group of main web, cover and insert sheets to the transfer cylinder 17, will first take a cover sheet from the cylinder 11 they will then collect thereon a group of main web sheets from the repeated coaction with the cylinder 7, and they will then take an insert sheet on top of the collected group of main web sheets. They will finally transfer this so collected and associated group of main web, cover and insert sheets to the transfer cylinder 17. During the repeated opening of this set of end grippers, their corresponding set of side grippers will close upon the sheets on the cylinder 8 and hold the sheets from slipping out of register, thus maintaining absolute control of the sheets at all times until they are transferred to the folding cylinder.

Vhile Ihave disclosed my invention as applied to a five-way combined collecting and associating cylinder arranged to collect four main web sheets or groups of sheets and associate a cover insert sheet therewith, it is obvious that I do not wish to limit myself to this particular arrangement.
